There was a problem filtering reviews right now. Please try again later.
The caveats here are that in some of the mats I purchased, there is a dial that allows you to increase or decrease overall heat for the mat, and that's useful only if you aren't using a soil temp probe to get exact heat temps. The cords are long enough that I can use them.
You CAN place steel or aluminum trays over these to provide a cleaner surface; I don't recommend it, because the additional thermal mass will take longer to heat up and more heat will be lost in an open system.
I -highly- recommend using these on a flat wooden surface. If, like I do, you repurpose metal storage racks with grid shelving, you will want to add a flat piece of metal or water-resistant plywood for these to sit on rather than allow them to drape on the grid. They work better at reflecting and retaining heat with plywood than metal. I worried a bit about electric shorts, but realized that the wood simply won't get that hot, and if there is an issue, my GFCI surge protectors plugged into the power strip will handle it long before it becomes an issue.
I have yet to try these in an insulated box, cabinet, or tent; my guess is that my soil temps could easily rise.
Water hasn't been an issue at all. The mats wipe off instantly and even when a small pool has sat for a few days, it hasn't been a problem. Cleaning them? Just regular spray cleaner and water wipedown.
I also used two of these in outdoor greenhouse/leantos during the spring and summer of 2022 as additional heat for pepper plants and tomatoes. They kept temps at the right heat levels to make it possible to grow habaneros and Ajio Limon in the fickle Seattle temp variations.
Things that could be better:
The cords are sufficiently long to use but it would make me much happier to have the cords start at the corner of the mat rather than the middle of one of the ends.
They tend to curl up at the ends if they're unplugged for some time. Part of that is just the natural shrinkage of plastic and metal when it's colder; still, the design could be improved a little.
All in all, a solid heating mat for the price and size. If it survives six years or more, I will count these well worth the money.
Reviewed in the United States on February 23, 2024
Their products just feel like quality and they perform just as good as they feel. I’m so glad they have focused so much on their line of indoor gardening equipment because it gives growers a high quality option.
Anyway, these mats are perfect! I grow thousands of out her plant seedlings and I prefer to use a heat mat while germinating them. The past few mats have fallen short because they use a thermostat that must be inserted into the soil to read the temp. While this may not seem like a big deal, I’ve had the sensor come out before and narrowly avoided frying my seedlings!
These mats however use a dial that you can tune to perfectly set your desired temperature (I use a laser thermometer for soil temps) not only is that helpful but it makes it much simpler to achieve your desired results.
Another thing I really like about these mats is they are not bulky at all. The technology they use is infrared and not heat coils. Which means it’s EVEN HEAT and with no hot spots like coil mats have. I feel like that’s a much safer option as heat coils, while rare, can short out. They do take slightly longer to reach peak heat but does a few extra minutes really matter when germinating seeds? Not really.
If you are looking for a high quality heat mat that will outperform any others you’re going to find, just do yourself a favor and go with these. They won’t disappoint!!
